This system is incorporated with an MP3 decoder. You can playback
MP3 tracks (files) recorded on CD-Rs, CD-RWs, and CD-ROMs.
• Notice that "files" and "tracks" are used interchangeably.
What is MP3?
MP3 is an abbreviation of Motion Picture Experts Group (or MPEG)
Audio Layer 3. MP3 is simply a file format with a data compression
ratio of 1:10 (128 Kbps*). That means, by using MP3 format, one
CD-R or CD-RW can contain 10 times as much data volume as a
regular CD can.
* Bit rate is the average number of bits that one second of audio data
will consume. The measuring unit used is Kbps (1000 bits per
second).
To get a better audio quality, choose a higher bit rate. The most
popular bit rate for encoding (recording) is 128 Kbps.
MP3 File Compatibility
• This system can only read MP3 files that are recorded in the
format that is compliant with ISO 9660 Level 1 or Level 2.
• The system can play MP3 files only with the following file
extensions: ".MP3;' ".Mp3," ".mP3," and ".mp3."
• This unit can show ID3vl * tags on the TV-screen.
• An MP3 file can contain file information called "ID3 Tag" where
its album name, performer, track title, etc. are recorded. There are
two versions--ID3vl (ID3 Tag version 1) and ID3v2 (ID3 Tag
version 2).
• This unit is not compatible with ID3v2.
Disc structure--How are MP3 files recorded
and played back?
"MP3 files (tracks)" can be recorded in "folders," in PC
terminology.
During recording, the files and folders can be arranged in a way
similar to arranging files and folders of computer data.
"Root" is similar to the root of a tree. Every file and directory can be
linked to the root.
In compliance with ISO 9660, the maximum allowable depth of
nested folders--so-called "hierarchy"_is eight (inclusive of the
root).
Playback order, files search order, and folder search order of the
MP3 files recorded on a disc are determined by the writing (or
encoding) application; therefore, playback order may be different
from the one you have intended while recording the folders and the
files.

NOTES for MP3 disc
• MP3 discs (either CD-R or CD-RW) require a longer readout time.
(It differs due to the complexity of the folder/file configuration.)
• When an MP3 disc is loaded, you cannot adjust the subwoofer
output level.
